Supersymmetry plays a fundamental role in the radiative stability of many inationary models. Spontaneous breaking of the symmetry inevitably leads to elds with masses of order the Hubble

Cosmological Moduli and the Post-Inflationary Universe: A Critical Review (2015, background): “Firstly, if the mass of the modulus is above the Hubble scale during inflation mσ > HI , which may be argued to be generic [181, 182], then in a single Hubble time the amplitude of its fluctuations will be exponentially suppressed on large scales by a factor exp(−m(2)σ/(3H(2) I )) and so the inflato”
Inflation and String Theory (2014, background): “For MSUSY < H, supersymmetry is only spontaneously broken during inflation, and can partially protect against radiative corrections (see [239] for a recent discussion).”

In fact, the same reasoning applies to the coupling to scalar elds, which is why the single-exchange diagram has been neglected in the context of quasi-single-eld in ation [8,9]. This fact, however, is only tied to spins zero and one, and the bispectrum does not have to be ”
